Hi

I'm interested in playing with this. Knowing nothing about the technology I searched for an Android HCCB reader to try out your sample. I found the Microsoft Tag app, but this fails to recognise your sample HCCB - just keeps refocusing. It does recognise other (simpler?) codes (though resulting in a screen saying "this code is no longer active" message, then forwarding to ScanLife), such as this.

Do you have a reader that works with your codes?

Hi Sam, the reader may actually work, but because I haven't implemented the ECC (error correcting code) portion, it probably can't establish a correct read. I have not created a reader at this time.

Any hopes for this? Pretty please?

I don't have the specs for HCCB. Does anyone know how it does ECC?

Is this still alive?

Not really. Feel free to use, adopt, or repurpose though.

According to the pattern System and method for encoding high density geometric symbol set, I think they are using Reed-Solomon error correction and the correction is put at the head to the code
